1 Answers
Leaving the car lights on after turning off the engine will consume battery power. Car batteries can be divided into traditional lead-acid batteries and maintenance-free batteries, which are an essential part of a vehicle. After the engine is turned off, the generator stops working, and the only power source for the entire car is the battery. Hazards of leaving lights on after turning off the engine: If the headlights are left on for a long time, it can easily lead to battery depletion, shorten the battery's lifespan, and affect engine startup. How to avoid leaving lights on after turning off the engine: It's best to check whether any electrical devices are still on before getting out of the car each time. If the car headlights have an automatic shut-off function, they will turn off automatically after the engine is turned off. During long-term use of the car, due to driving bumps and vehicle washing, it is inevitable that headlight grounding short circuits may occur, screws at various fixed points may loosen and rust, increasing circuit resistance and causing dim headlights. The general method to avoid such increased resistance is cleaning and tightening. Types and functions of car lights include: Brake lights: Warn people or vehicles behind; Turn signals: Alert vehicles and pedestrians in front, behind, and to the sides; License plate lights: Illuminate the car license plate at night; High beams: Check distant road conditions; Low beams: See the road conditions in front of the car; Fog lights: Have strong penetration in fog, making it easier for vehicles and pedestrians to notice early; Daytime running lights: Draw attention from other traffic participants; Hazard warning lights: Alert vehicles behind to yield.
